What the vulnerability does
The Word Replacer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'replacement' parameter in all versions up to, and including, 0.4. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
Word Replacer versions 0.4 and earlier contain an input validation flaw that allows high-privilege users to modify site content across scope boundaries. An attacker with administrative access can alter text replacements in ways that affect other components or users. The vulnerability requires high attack complexity and administrative credentials to exploit.
What an attacker can do
Modify site content or text replacements in ways that affect other users or system components.
Potential impact on your site
An admin account compromise could allow unauthorized changes to site content visible to other users.
Conditions required to exploit
Attacker must have high-level administrative privileges on the site.
